QR Code in solidworks
I was looking for easy way to get QR code in 3D model within solidworks. Here’s one recipe hot to do it.
First, get to some online QR code generators, which could export vector graphics, e.g. PNG, SVG, EPS, or similar format. I picked up the first link via google search: http://qrcode.littleidiot.be/
Let’s put some simple “test” into QR code via SVG file. It is obvious, the QR generator compose the QR code with small squares at their proper positions. The squares grid and size are equal, which may cause troubles when used in extrude feature within solidworks. To avoid that, squares should be scaled individually. Open the SVG file in inkscape and scale all squares:
- select the drawing
- ungroup
- select scale 95% for width and height
- check the option “Apply to each object separately” and press Apply
The QR code should look something like this (with gaps between squares):
The preparation is finished by saving the drawing into DXF file.
Now start new part by extruding a square. Place DXF on top face and move the drawing to origin:
Extrude cut to e.g. 1mm:
Repeat DXF insertion once again and align the drawing to the origin (or alternatively, convert the extrude edges into line entities):
Use the drawing to cut extrude with the thin feature, which cut the walls away. Change the solid color to black and top surface to white:
I’ve been trying this for a few hours now. I saved my QR code as a DXF file and inserted to the face of my extruded square, I went through the insertion wizard but nothing seems to happen??
I tried this as well, inkscape generates a file that is 0kb, unusable.
Inkscape has received additional data from the script executed. The script did not return an error, but this may indicate the results will not be as expected.
